| Abstract:
The high cost of heating greenhouses due to escalating fuel costs has created a crisis situation in the greenhouse industry. As a result, interest in methods of energy conservation, in alternate less costly sources of energy, and in plants which grow satisfactorily in cooler environments has become intense. Energy can be conserved by use of night curtains, by use of heavy insulation in the north wall of greenhouses and by the increase in the number of layers of glazing, particularly on the south side and end walls. The increased use of waste energy and solar energy as alternative energy sources and for reducing energy requirements has received particular attention and both can be effectively utilized. As a result of the activities of engineers and innovative greenhouse operators, a number of viable alternatives are now available to greenhouse operators for reducing their energy costs. | |
